At best, WBD could have gone bankrupt and a court order could require it to be sold as parts with no one studio getting a significant chunk, scattering WBD's IP moat across many competitors.
But most likely it just means someone like Netflix would have the chance to make a smaller offer for the same kind of deal on a WBD with a worse negotiating position. Same consequences, different day.
But more drawn out. This way, creatives, consumers will get a reinvigorated outlet, rather than seeing it spiraling downward.
